MOLD-HANDLING APPARATUS.

Specication of Letters Patent.

Application led January 8, 1921. Serial No. 435,853.

T 0 all 'zo/1.0m t may concern.:

Be it known that I, EDWARD D. CARY, a citizen of the United States ofAmerica, residing at New York, in the county of New York and State ofNew York, have invented certain new and useful improvements inMold-Handling Apparatus, of which the following is a specification.

This invention relates to a mold handling and conveying apparatus,designed particularly to be used in conjunction with any type of brickmolding machine., and adapted in use to direct the molds into properposition with respect to the brick machine, to thereby receive thematerial, convey such molds from the brick machine and discharge thebrick from the molds, direct the discharged brick to a point ofdischarge, convey the empty molds to a sander in which the interior ofthe mold is sanded to prevent the brick material sticking thereto, anddeliver the sanded mold into proper position with relation to they brickmachine, thus completing a cycle of operation.

The improved machine is entirely automatic in its operation with allparts driven, if preferred, from the motive power of the brick machine,and each and every part of the improved apparatus turned with relationto every other part and operated entircly without the use of chains,gears, belting or the like with the advantage of avoiding irregularityof operation and the frequent necessity for repair and adjustmentnecessitated by such particular driving' means.

In the drawings Fig. 1 is a side elevation of the improved apparatus.

Fig. 2 is a longitudinal central section of the same.

Fig. 3 is an enlarged transverse' section on line of Fig. 1.

Fig. l is a rear end elevation of the machine.

F ig. is a perspective view showing the operating means rfor the variousmoving parts of the apparatus and for compelling the travel of the mold.

Fig. 6 is a perspective view showing the mold secured upon the sandingwheel.

Fig. 7 is a detail perspective showing the operation of the feedingfingers.

Fig. 8 is a transverse section of the same.

The apparatus comprises a main frame 1 which for the sake of the presentdescription may be said to comprise an upper trackway 2 and a lowertrackwayY 3. A brick machine 4 of any usual or preferred type is mountedso as to discharge the material therefrom onto the upper trackway at aparticular point to be hereinafter referred Patented Aug. s, i922.

to, and the respective parts of the apparatus to be described arearranged with more or less particular relation to such brick machine.

The shaft 5 is mounted in suitable bearings on the upper trac-kway inrear of the bric-k machine, considering the direction of movement of themolds, and on this shaft areV fixed spaced discs 6, having alignedrecesses 7 of a size and shape to receive the mold. The'discs togetherconstitute whatwill b-e hereinafter termed the mold positioning wheel,and the recesses, preferably four in number and arranged indiametrically opposed pairs, receive the mold and deliver the same intoa position to be moved beneath the brick machine.

A shaft 8 is mounted in the upper trackway in advance of the brickmachine on which is arranged spaced discs 9 together constituting whatwill be hereinafter termed the mold reversing wheel, these discs beingformed with mold receiving slots or recesses 10, also preferably four`in number relatively offset from `the diametric line as shown. The uppertrackway 2 in advance of the mold reversing wheel is in the form or adownwardly and forwardly inclined gravity conveyor 11, made up of sidesupports and a series of freely rotatable rollers 12 constituting thebed of such conveyor. This conveyor extends between the discs 9 of themold reversing wheel and terminates at the opposite end for a properdischarge. The end of the conveyor between the discs of the moldreversing wheel is on a plane llower than that of the trackway beneaththe brick machine, so that as the molds are reversed by the wheel andthe bricks delivered therefrom on the pallet vboard support, saidsupport and bricks will also having a roller bed Q0 by which the mold isdirected back onto the lower trackway Bof the main frame. 1

The molds` are carried lengthwise1` the `lower trackway to the forwardend o the mainframe and are there delivered to a sandingwheel ,21Vthrough which they are sanded and delivered to the positioning wheelherein beiore referred to.` llie `mold and various wheels such as `thepositioning wheel, `reversing wheel, discharge wheel and sandingr wheelare operated automatically and givena periodic limited move` ment ineach `step by step operation l of the machine, and the mechanism vforperforming these` various y operations will now be described. which is`given a reciprocating movement through suitable connection with thedriving mechanism of the brick machine.y or in`de` pendent power may bedesired, rocks a shaft 23 supported in suitable bearings in the mainframe between the upper and lower trackways and `preferably beneath thebrick machine. An operating bar 2Liis movably supported upon a traineelement 25 andcarries, by means oli uprights 9,6, pivotally mountedpawlsiQ, l28 and` 29. Tliesefpawls are each formed on their lower sidesto presentihooks 30` andwith extended nose portions 3l in advance oi'the hooks.` rlllhe respective `pawls 27, QBand 29 are arranged adjacentthe positioning,` reversing andi discharge wheels, and such wheels areprovided with diainetricallyg opposed arms 32 having lateral pins 33tolie-engaged by the hookportions 30 of the;par\vls. `The lhan 24-` isprovided with `a lateralA pin ll-extendng through slot `35 in the framebar 25 and `connected by afliiik 36 with antarin 37 cured to the rockshaft `23. As the shai't 23 is rocked in the operation of the device,the

respective. pawls 27, 28 and 29` will engage.

The positioning, reversing and discharge wheels are thus advanced by astep by step movement through a` quarter or a revolution at eachmovement. A corresponding pawl 38 supported in a traine bar 3 9 andoperated by a link llllro'm zi-rind( is arranged to enthe pins ell. orthe sanding wheel, to thus simultaneously advance` the sanding wheel ina step by step movement through a onequarter revolution.`

The trai-elr ofthe inolds along the lower trackway 3 is also providedfor through a series `oil dogs 48 pivotallysupported bef tween bars.l-Qniovablyzmoiinted in the lower ends elevated above the trackway andoperated through links `50 las described in `connectionu.with the y dogs45. The links `50 are actuated through a rod `5l "connected by bars 52with"I the` arm' 37 and with the corresponding'arm 5? at the op- 1'posite end of the `rocksha'tt 23.` The fmolds lare thus given a step bystep movement' `lengthwise `the low-er'trackway, the reverse movementoitthe linksl'O permitting the dogs -to drop to ride-beneath the nextmoldr to be engaged, will be obvious.

The end of thelower trackway adjacent lll) the sandingwwheel terminatesin a downi wardly inclined section 54 bywhichthe molds are turned anddirectedonto the-.sanding wheelwith their open ends .or `'faces againstsaid wheel. The sanding wheel is provided.

`with transverse abutments and 56 between which. thefmold iszfreeeived,and gripping ,members are arranged to hold the n10-ld, in 13@ properposition on the sanding Wheel during movement of said Wheel. rlhesegripping members comprise arms 57 having hook ends 5S to engage over theends of the mold, the opposite end of the arms having rollers 59 to bearupon lixed trackvvays 60 to press the hook ends the arms into holdingrelation with the mold. s the mold reaches the uppermost position on thesanding Wheel it is free of holding connection with the Wheel, as theprevious termination ofthe trackvvays 60 permits the arms 57 togravitate to a release position. The discharge position of the sandingWheel is immediately adjacent the positioning ivheel, there beingarranged intermediate the sanding Wheel and positioning Wheel spacedlingers 6l, up Which the mold is forced by the movement of the sandingWheel, and the bar 56 to the plane of the recess in the positioningWheel. A mold resting upon these fingers is of course forced into thepositioning Wheel recesses by the next or succeeding mold of the sandingWheel, as ivill be apparent.

The molds are forced from the reversingI Wheel through a plunger 62slidably mounted upon the shaft 8 and held for reciprocating movementbetween guides 63. The forward end of the plunger is in position toeject the mold from the recesses of the reversingr Wheel next the armsof the discharge Wheel,v the ejecting movement of the plunger being`provided through Contact of the advancing mold from the brick machine.There is a plunger on each disc, each cooperating With tivo slots, sothat after ejecting movement the turn of the Wheel positions the plungerfor the succeeding operation.

The shaft 65 on which the sanding Wheel is rotatably mounted is hollovvand formed with a series of openings 66 ivithinthe plane of the vvheel,the shaft communicating With the sand supply, so that sand is deliveredinto the mold when in lowermost position on said Wheel for sandingpurposes, the sand accumulating in the Wheel being readily distributed,that is shakeninto and out of the moldv during movement of the sandingWheel in order that the mold may be propei'ly sanded.

r he mold is of usual form here shown as comprising a box like member 67having brick or other compartments 68. and provided with end extensions69 which may or may noiy be solid or otherwise built up, the extensionsproviding` the additional length of mold necessariY to permit suchmoldto be properlyv supported in the recesses and arms of the respectiveWheels, While having the brick or other molded material arranged Whollybetween the discs forming :such Wheels. This is essential as in the useof the reversing Wheel the molds are carried from said Wheel onto thearms of the ldischarge Wheel and picked up leaving the .versed onto theconveyor l1.

brick on the pallet in contact 'with' the i 1n the operation of thedevice, the posi-y tioning Wheel, receiving in'its successive recessesthe molds from the sanding Wheel, deliver suchl molds onto the uppertrack- Way along which they are forced to a position beneath the brickmachine and receive the material therefrom. The molds as they leave thebrick machine are provided `with a pallet 70 by the operator and thendelivered into the reversing Wheel and reresting on the pallet are thusdischarged and moved off on the conveyor by gravity7 to a point ofdischarge. Themolds are picked up by the arms of the discharge Wheel anddelivered onto the mold conveyor, and so on to the vlower trackvvay. Themolds are fed ,in succession lengthwise the lower trackway to thesanding Wheel, properly7 sanded and delivered to thepositioning Wheel,thus completing the cycle of movement.

It will be noted particularly that all parts The bricksof thelapliaratus herein described are operi ated `Without the use of chalins,belts, sprockets or the like and that every movement is coordinated withevery other move- `ment so that it is impossible for the machine toget-out of time in its respective Z operations, and also the necessityfor repair andy renewal incidentl to ordinary modes of ydrivingmechanism is obviated.
